Electron hole

An electron hole is the absence of an electron at a position where one could exist in an atom.



The electron hole has absolute values of the same charge as the electron but, contrary to the electron, its charge is positive.

It is a simple way to analyze the motion of a large number of electrons by treating this absent electron as a quasiparticle.



The notion of "hole", was developed by the German physicist Werner Heisenberg in 1931.
